According to the Foliated Metamorphic Rock Chart slate, phyllite, schist, and gneiss can all have the same parent rock (shale). If this is true, what determines the difference between a slate and a gneiss rock that both are formed from shale? What role does the parent rock play in determining the type of metamorphic rock that will be formed? In a rock that has undergone contact metamorphism, would you expect to find foliation? Why or why not? State your answers in 3-5 sentences.
please answer simply! Thank you so much! I will name brainiest!
The difference between a slate and a gneiss rock that are both formed from shale is due to the degree and type of metamorphism they undergo. Slate has undergone low-grade metamorphism, while gneiss has undergone high-grade metamorphism.
The parent rock plays a role in determining the type of metamorphic rock that will be formed as the mineral composition and texture of the parent rock will affect the metamorphic process.
What is the rock about?In a rock that has undergone contact metamorphism, foliation may or may not be present.
Foliated metamorphic rocks, such as slate, phyllite, schist, and gneiss, are formed when the rock is subjected to directed pressure, which aligns the minerals in a parallel or foliated pattern.
However, contact metamorphism is caused by heat and typically does not involve directed pressure, so foliation may not be present in rocks that have undergone contact metamorphism.

If the population size of a host decreases, the way that it will affect the population size of its parasites is option D: The parasite population will decrease in size.
What is the population size about?Parasites rely on their host for survival and reproduction, so a decrease in the host population size will result in a decrease in the resources available for the parasite population. The decrease in host population size will also lead to a decrease in the number of hosts available for the parasite to infect, which will further decrease the parasite population.
Therefore, It's important to note that the relationship between host and parasite populations is complex and can be affected by other factors such as the host's susceptibility to infection, the parasite's virulence, and the presence of other parasites. However, in general, a decrease in the host population size will lead to a decrease in the parasite population size.

Name and describe one of the three conditions Dr. Natterson-Horowitz mentions that have been well-studied by veterinarians, who might have insights to provide in diagnosing or treating those conditions in human patients.
Do you find Dr. Natterson-Horowitz’s argument that physicians can learn a lot from veterinarians convincing? What part of her argument is, to you, especially strong or weak?
Let’s play devil’s advocate. What are two arguments you would use to support the claim that medical doctors and veterinarians do not need to collaborate in the way that Natterson-Horowitz is suggesting?
Natterson-Horowitz mentions several programs that she works with to “close the gap” between medical doctors and veterinarians. What is another way that these two fields could collaborate?
Dr. Natterson-Horowitz is a cardiologist at UCLA and a contractor who helped the Los Angeles Zoo, she realized that the divide between treatment of humans and animals in contemporary society.She explains that one of the reasons for this divide is that medical doctors and veterinarians have traditionally been trained in separate disciplines, with little overlap or communication between the two.
One of the three conditions Dr. Natterson-Horowitz mentions that have been well-studied by veterinarians, is cancer, veterinarians have been studying cancer in animals for decades and have developed treatments and therapies that are now being applied to human patients.
What other thing does Dr. Natterson-Horowitz do?Dr. Natterson-Horowitz's argument is that physicians can learn a lot from veterinarians. One of the strongest points in her argument is that veterinarians have been studying diseases and conditions for decades in animals, and their findings can be applied to human medicine.
One argument against the claim that medical doctors and veterinarians do not need to collaborate is that the anatomy and physiology of animals are different from that of humans, and what works for animals may not work for humans. Another argument is that medical doctors and veterinarians have different priorities and goals, with medical doctors focusing on human health and veterinarians focusing on animal health.
Therefore, Another way that these two fields could collaborate is by creating a program that allows medical students to spend time in the field with veterinarians, and vice versa, to gain a better understanding of each other's work and the similarities and differences between human and animal medicine.

The human heart is sometimes described as a double pump because of its left and right sides , rather than because of its upper and lower chambers . Explain why
Human heart half of the heart pump more blood around a separate circulatory system, it is characterized as a double pump. While the left side circulates blood the right side delivers blood to the lungs.
Why is the heart referred to be a double pump?Despite being a single organ, your heart has two pumps. The first pump sends blood that is low in oxygen to your lungs, in which it sucks up oxygen and releases carbon dioxide. After that, it returns oxygen-rich blood to your heart. Every region of your body receives blood that is oxygenated thanks to the second pump.
Why are the heart's two pumps positioned side by side?Blood that is deficient in oxygen is delivered to the right atrium of the heart because most of it has been exhausted by the body and brain. Your lungs then take in a new supply of oxygen as a result of this being pumped to them. In order to be recycled back to the mind and the remainder of your body, the blood then travels down to a side of the heart.

Why is it not totally surprising that animals can suffer from emotional distress or mental illness?
The video discusses giving animals human medications like anti-anxiety or anti-depression drugs. Do you think animals should be treated with drugs used for mental illness? Why or why not?
Briefly describe at least two of the disorders that Braitman explains animals can suffer from.
Why do veterinarians often ask about an animal’s behaviors and life during an office visit?
Why does Braitman say that we owe our entire psychopharmaceutical arsenal to animals? Explain.
How could thinking about an animal’s mental health influence veterinary care?
Braitman became interested in mental illness in animals because she observed that her own pets were displaying symptoms similar to human mental illnesses.
It is not surprising that animals can suffer from emotional distress or mental illness because they are living beings with brains and nervous systems that are capable of experiencing emotions and responding to stressors in similar ways to humans.
The use of human medications for animals is a controversial topic. Some argue that it is necessary to provide animals with the same level of care and treatment as humans, while others argue that animals may have different physiological responses to these drugs and that more research is needed before administering them.
Two disorders that Braitman explains animals can suffer from are separation anxiety and compulsive disorders.
Veterinarians often ask about an animal’s behaviors and life during an office visit because it can provide insight into the animal’s emotional and psychological well-being and can aid in diagnosis and treatment.
Braitman says that we owe our entire psychopharmaceutical arsenal to animals because animals have been used in the testing and development of many of the drugs used to treat human mental illnesses.
Thinking about an animal’s mental health could influence veterinary care by leading to more comprehensive and holistic treatment plans that take into account not just the physical symptoms, but also the emotional and psychological well-being of the animal.
What is the medication about?Regarding the use of human medications for animals, it is important to consider the potential benefits and risks of administering these drugs to animals. On one hand, administering anti-anxiety or anti-depression drugs to animals could provide relief from symptoms and improve their quality of life.
On the other hand, there is a lack of research on the safety and efficacy of these drugs in animals, and administering them could have unintended consequences. Additionally, animals may have different physiological responses to these drugs than humans, which could lead to ineffective treatment or adverse reactions.
